Chen Wei had been fishing the same waters off Taiwan’s coast for thirty-seven years. His weathered hands knew every current, every reef where grouper liked to hide. But on a humid morning last August, something felt wrong. The water looked the same—that familiar gray-green of the Taiwan Strait—but the silence was deafening.
No gulls. No other boats on the horizon. Just the distant rumble of military vessels conducting “exercises” in what used to be his family’s fishing grounds. Chen’s catch that day: nothing. The fish had vanished, spooked by underwater explosions and sonar pings that turned their ancient migration routes into chaos.
“Thirty-seven years,” he told his wife that evening, staring at his empty nets. “The sea never felt afraid before.”
When Military Strategy Rewrites Ocean Maps
Chen’s story isn’t unique. Across the contested waters of the South China Sea and around Taiwan, China’s military dominance strategy is transforming entire marine ecosystems into weapons testing zones. What environmental scientists call “militarization of the ocean” is happening faster than most people realize.

Beijing’s approach to securing these waters goes far beyond deploying warships. They’re systematically converting traditional fishing grounds into military exclusion zones, conducting live-fire exercises that scatter marine life, and building artificial islands that destroy coral reefs dating back thousands of years.
“We’re witnessing the largest peacetime disruption of marine ecosystems in modern history,” says Dr. Sarah Chen, a marine biologist who has studied these waters for over a decade. “The military sees empty ocean. But there’s nothing empty about it—these are some of the world’s most biodiverse waters.”
The numbers tell the story. Since 2016, China has declared over 200 separate military exercise zones in the South China Sea alone. Each declaration typically lasts 3-7 days, but the ecological impact stretches for months as marine life struggles to readjust migration patterns.
The Hidden Cost of Naval Exercises
The environmental damage from China’s military dominance campaign operates on multiple levels, each more devastating than most headlines suggest:
- Underwater explosions from missile tests and torpedo practice destroy fish hearing and navigation systems
- Sonar operations can cause mass strandings of whales and dolphins up to 200 miles away
- Military vessel traffic disrupts breeding grounds and feeding areas for endangered species
- Fuel and chemical spills from increased naval activity poison critical marine habitats
- Artificial island construction buries entire coral reef ecosystems under millions of tons of sand
The timing couldn’t be worse. These waters already face pressure from overfishing, climate change, and pollution. Adding military stress to already fragile ecosystems is pushing many species toward local extinction.
| Military Activity | Environmental Impact | Recovery Time |
|---|---|---|
| Live-fire missile tests | Fish population drops 40-60% | 6-18 months |
| Submarine sonar exercises | Marine mammal strandings increase 300% | 2-5 years |
| Artificial island construction | Coral reef destruction (permanent) | Never recovers |
| Fuel spills from naval vessels | Seabird deaths, water contamination | 3-10 years |
“Every major exercise leaves a footprint that lasts years,” explains Dr. James Rodriguez, who tracks maritime environmental damage. “We’re not talking about temporary inconvenience. We’re talking about permanent changes to how these ecosystems function.”
Fishing Communities Caught in the Crossfire
The human cost runs parallel to the environmental destruction. Fishing communities across the region watch their traditional grounds disappear behind military barriers, often with just hours of warning.
In the Philippines, fishermen report being turned away from areas their grandfathers fished by Chinese Coast Guard vessels. Vietnamese fishing boats face similar restrictions, forced to venture into more dangerous waters or accept smaller catches from depleted near-shore areas.
Taiwan’s fishing industry has been hit particularly hard. During the August 2022 military exercises following Nancy Pelosi’s visit, satellite data showed fishing activity dropped by 85% in affected areas. Many boats never returned to their original fishing grounds, either because they were permanently restricted or because the fish populations never recovered.
“We’re not talking about temporary military exercises anymore,” says Captain Lin Zhao-ming, who represents over 300 fishing families in northern Taiwan. “These are permanent changes to how we can use our own waters. Fish don’t understand military boundaries, but they understand when their world gets turned upside down.”
The economic impact spreads beyond individual fishermen. Processing plants, marine equipment suppliers, and coastal communities built around fishing traditions find themselves adapting to a new reality where the ocean belongs more to military strategists than to the people who depend on it for survival.
The Bigger Picture Nobody’s Discussing
China’s military dominance strategy in contested waters represents something larger than regional tensions. It’s a preview of how military competition will reshape marine environments worldwide as nations prioritize security over sustainability.
The pattern is spreading. Similar militarization is occurring in the Baltic Sea, where NATO and Russian exercises increasingly overlap with critical marine habitats. The Arctic Ocean faces growing military activity as ice melts expose new strategic waterways.
“We’re entering an era where military planners treat oceans as empty space to be controlled rather than living systems to be protected,” warns Dr. Maria Santos, an expert on military environmental impact. “The long-term consequences could be irreversible.”
What makes China’s approach particularly concerning is its scale and persistence. Unlike traditional naval exercises that last days or weeks, Beijing’s military activities in contested waters operate on a continuous basis, creating permanent ecological stress.
The artificial islands alone have destroyed over 3,000 acres of coral reefs—ecosystems that took centuries to develop and support thousands of species found nowhere else on Earth. The military value of these installations may be strategic, but their environmental cost is incalculable.
FAQs
How do military exercises actually harm marine life?
Underwater explosions damage fish hearing and navigation, while sonar disrupts whale and dolphin communication systems. Many species avoid these areas permanently after experiencing military activity.
Can damaged marine ecosystems recover from military activities?
Some impacts like fish population disruption can recover over months or years. However, destroyed coral reefs and buried seagrass beds represent permanent losses that take centuries to naturally restore.
Are there international laws protecting marine environments during military exercises?
Limited protections exist, but enforcement is weak and many military activities occur in disputed waters where no single authority has clear jurisdiction.
How does this affect global fish populations?
The South China Sea provides 20% of the world’s fish catch. Disrupting breeding and migration patterns here impacts global food security and fish populations worldwide.
What alternatives could reduce environmental damage?
Military exercises could be scheduled around breeding seasons, conducted in already-degraded areas, or use simulation technology instead of live munitions in sensitive habitats.
Do other countries cause similar environmental damage with military activities?
Yes, but the scale and frequency of China’s activities in contested waters currently represents the largest ongoing military impact on marine ecosystems globally.
